Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are eternally enriched. Their positions at the foot of watersheds and their convenience as receiving bodies for the wastes of cites, towns and farms results in continuous addition of nutrients - those elements and compounds which are essential for organic production. Such materials must be added to these complex bodies of water to sustain production, since there is a net loss of water and its contents to the oceans. Enrichment from land and the ocean and the subsequent cycling of the original chemicals or their derivatives contribute to the extraordinarily high values of estuaries for human purposes. Many estuaries are able to assimilate large quantities of nutrients despite the great fluctuations which occur with variations in the flow from tributaries. The nutrients can be stored, incorporated in standing crops of plants, released, cycled and exported - and the system frequently achieves high production of plants and and animals without creation of any undesirable results of enrichment. Excessive enrichment with the same elements and compounds can, however, be highly detrimental to estuaries and their uses. Coastal cities are usually located on the estuaries which provided a harbor for the- and which now receive partially treated sewage and other wastes from the expanding population and industrial activity. Conversion of woodlands to agricultural use and the extensive application of fertilizers have resulted in the flow of large quantities of nutrients down the hill or slopes and eventually into the estuary.

Available in PDF, EPUB and Kindle. Book excerpt: Coastal transitional ecosystems include a wide range of morphological features—i.e., lagoons, wetlands, estuaries, deltas, and so on. According to the Ramsar Convention, “they are among the most diverse and productive ecosystems” and are continually “degraded and converted to other uses”. To protect and restore these highly valuable ecosystems, knowledge of their processes and the assessment of their ecological conditions under anthropogenic pressures is of fundamental importance. The present book contains eight original research papers and a review that provide useful tools to understand the structure and function of transitional waters worldwide. The results allow us to assess the impact of anthropogenic activities and inform stakeholders on the actions that can be taken to manage them. The papers in this book provide different ecological approaches to investigate some main impacts: - benthic and nekton communities were studied to assess the impact of eutrophication and salinity changes; - biological processes in carbon dioxide fluxes were assessed in the framework of climate change; - nekton communities were discussed in relation to habitat morphological degradation; - the role of invasive alien species was considered.
Download or read book Estuarine Processes written by Martin Wiley and published by Academic Press. This book was released on 2014-05-10 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuarine Processes, Volume I: Uses, Stresses, and Adaptation to the Estuary provides information pertinent to estuarine processes and focuses on dynamic interactions at several levels of organization. This book presents the strategies to rehabilitate and protect estuaries. Organized into seven parts encompassing 37 chapters, this volume begins with an overview of the alternative ways of attaining the pervasive goals of pollution abatement and estuarine management. This text then discusses the significance of maintaining estuarine environment quality if fisheries are to continue. Other chapters consider the great value of the estuarine zone, which lies in the multiplicity of uses it serves, but herein also lies its vulnerability. This book discusses as well the identification of the major factors regulating phytoplankton productivity and regulating the level of phytoplankton biomass. The final chapter deals with assessing the potential deleterious effects of certain toxicants to penaeid shrimp. This book is a valuable resource for ecologists, environmentalists, and scientists.
Download or read book Estuaries written by Peter J. Wangersky and published by Springer Science & Business Media. This book was released on 2006-01-10 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aspects of the biogeochemistry of estuaries from a variety of environments, from the tropics to the Arctic, are discussed. In most cases the courses of these rivers have been altered by dams or diversions; the results of these changes on the nature of the estuary are also discussed, where such data is available. In the case of the Tasmanian rivers, the estuary of the Huon, a largely untouched river, is contrasted with that of the Derwent, a river heavily influenced by industry. The future state of all of these estuaries may be a sensitive indicator of shifts in global weather patterns.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

This book was released on 2012-12-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: All over the world, the awareness of the increasing pollution of rivers, estuaries and the sea with its associated impact on these ecosystems, its effect on organisms, food-chains, water supply and finally on man himself is growing. Estuaries form a link between the limnetic and marine environments, characterized by a variety of complex processes. Most of these phenomena are not yet sufficiently understood, making efficient water quality management a difficult task. The volume has two main objectives: to present the latest information on current estuarine research and to elaborate fundamentals and criteria for planners and decision-makers in water quality management.

Available in PDF, EPUB and Kindle. Book excerpt: Estuarine and coastal waters are acknowledged centres for anthropogenic impacts. Superimposed on the complex natural interactions between land, rivers and sea are the myriad consequences of human activity – a spectrum ranging from locally polluting effluents to some of the severest consequences of global climate change. For practitioners, academics and students in the field of coastal science and policy, this timely book examines and exemplifies current and future challenges: from upper estuaries to open coasts and adjacent seas; from tropical to temperate latitudes; from Europe to Australia. This authoritative volume marks the 50th anniversary of the Estuarine and Coastal Sciences Association. Drawing on the expertise of more than 60 specialist contributors, individual chapters address coastal erosion and deposition; open shores to estuaries and deltas; marine plastics; coastal squeeze and habitat loss; tidal freshwaters – saline incursion and estuarine squeeze; restoration management using remote data collection; carbon storage; species distribution and non-natives; shorebirds; Modelling environmental change; physical processes such as sediments and modelling; sea level rise and estuarine tidal dynamics; estuaries as fish nurseries; policy versus reality in coastal conservation; developments in estuarine, coastal and marine management. In addition to providing an overview of current scientific understanding, the material gathered here offers a clear-eyed perspective on what needs to be done to protect these fragile – and vital – ecosystems.
